Fred99:Batman:only 53% of Brits would definitely have vaccine while "about a third in certain groups won't" https://www.theguardian.com/world/2020/aug/09/only-half-of-britons-would-definitely-have-covid-19-vaccination
That's a serious problem. Of course anything from government to educate or encourage the public to get vaccinated becomes target for conspiracy theory - reinforcing their belief that microchips are being injected or whatever. Social media companies have failed society.
I dare say this figure is representative of the global picture. US and UK similar it's not just the US.
